Ki no Tsurayuki was a Japanese author, poet and court noble of the Heian period. He is best known as the principal compiler of the Kokin Wakashū, also writing its Japanese Preface, and as a possible author of the Tosa Diary, although this was published anonymously. He is well known for his waka poetry and is counted as one of the Thirty-six Poetry Immortals selected by Fujiwara no Kintō; his poetry was included also in the Hyakunin Isshu. As a courtier, he served as Governor of Tosa (930-935), Vice Governor of Kaga (917-923) and Vice Governor of Mino Province (918-923).
